## Abstract The highest concentration of 9βhydroxybenfluron (HBF) tested, namely 4Β·05 ΞΌmol1^β1^, induced immediate cytotoxic effects which were manifested by total inhibition of cell proliferation after only 24 h of culture. In a certain proportion of the cells cytolytic effects were observed at lo

THREE FIGURES
Strain HeLa cells, derived from an epidermoid cervical carcinoma (Gey, '52; Scherer et al., '53) are currently employed in this laboratory in studies of the physiology and biochemistry of poliovirus replication in animal cells. The use of manometry f o r determination of the metabolitic acivity of HeLa cells has been reported (Gifford et al., '54). This communication relates to the application of manometric procedure t o : (a) estimation of cellular growth, and (b) evaluation of some complex media and buffers for use on HeLa cell cultures.

Incubation of HeLa cells at 42Β°C results in pronounced inhibition of the accumulation of 18s and 28s ribosomal RNA (rRNA) and non-heat shock polyadenylated messenger RNA (mRNA) in the cytoplasm. Accumulation of transfer RNA and 5s ribosomal RNA is not affected. Transcription of rRNA precursor is red
